Total Allowable Axial Load for Short Columns Solution

STEP 0: Pre-Calculation Summary

Formula Used

Allowable Load = Gross Area of Column*(0.25*Specified Compressive Strength at 28 Days+Allowable Stress in Vertical Reinforcement*Area Ratio of Cross Sectional Area to Gross Area)
P_allow = A_g*(0.25*f'_c+f'_s*p_g)
This formula uses 5 Variables

Variables Used

Allowable Load - (Measured in Newton) - Allowable load is the maximum working load that can be applied on the structure.
Gross Area of Column - (Measured in Square Meter) - Gross Area of Column is the total area enclosed by the column.
Specified Compressive Strength at 28 Days - (Measured in Pascal) - Specified Compressive Strength at 28 Days is the capacity of a material or structure to withstand loads tending to reduce the size, as opposed to which withstands loads tending to elongate.
Allowable Stress in Vertical Reinforcement - (Measured in Pascal) - Allowable Stress in Vertical Reinforcement is equal to 40 percent of the minimum yield strength, but not to exceed 30,000 lb/sq.in(207 MPa).
Area Ratio of Cross Sectional Area to Gross Area - Area Ratio of Cross Sectional Area to Gross Area is the ratio of cross-sectional area of vertical reinforcing steel to gross area of column.

STEP 1: Convert Input(s) to Base Unit

Gross Area of Column: 500 Square Millimeter --> 0.0005 Square Meter (Check conversion here)
Specified Compressive Strength at 28 Days: 80 Pascal --> 80 Pascal No Conversion Required
Allowable Stress in Vertical Reinforcement: 4.001 Newton per Square Millimeter --> 4001000 Pascal (Check conversion here)
Area Ratio of Cross Sectional Area to Gross Area: 8.01 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_allow = A_g*(0.25*f'_c+f'_s*p_g) --> 0.0005*(0.25*80+4001000*8.01)

Evaluating ... ...

P_allow = 16024.015

STEP 3: Convert Result to Output's Unit

16024.015 Newton -->16.024015 Kilonewton (Check conversion here)

FINAL ANSWER

16.024015 ≈ 16.02402 Kilonewton <-- Allowable Load

What is Axial Load and Radial Load?

Load can be applied to bearings in either of two basic directions. Radial loads act at right angles to the shaft (bearing's axis of rotation). Axial (thrust) acts parallel to the axis of rotation.
